CROSS-REFERENCE TO RELATED APPLICATIONS

This invention claims priority, under 35 U.S.C. § 120, to the United States Provisional Patent Application No. 63/192,255 to Mai Lieu filed on May 24, 2021, which is incorporated by reference herein.

BACKGROUND OF THE INVENTION Field of the Invention

The present invention relates to hair cutting devices and methods, specifically hair cutting devices for cutting hair at home.

Description of the Related Art

In the related art, it has been known to use trimming guides to cut hair. Hair cutting and trimming guides allow for easy and accurate trimming of hair. Cutting guides allow for trimming of hair growing forward, generally known as the bangs, as well as for hair growing any direction and of any length.

Cutting hair is more like an art than a science. For this reason, countless techniques have been developed by hairdressers for cutting hair in an even and stylish pattern. Every hairdresser chooses their favorites from among these techniques and employs it in everyday practice.

One common technique is to grasp a group of hair between two fingers, and then cut parallel to the longitudinal surfaces of the fingers. This technique allows hair to be cut at a consistent length. Since conventional haircutting scissors are extremely sharp, this can be a dangerous practice.

At times, however, it is desirable to have such a group of hair cut at varying lengths. To do this, the scissors are angled inward toward the fingers to execute “point cutting” for textured blending. The danger of cutting toward the fingers is especially acute when point cutting. Accordingly, many hairdressers cut in such a manner without the benefit of the “reference line” created by the fingers. With practice, such cutting can be relatively consistent. Rarely, however, is the cut completely even. It is also difficult to perform on oneself or at home.

Some improvements have been made in the field. Examples of references related to the present invention are described below in their own words, and the supporting teachings of each reference are incorporated by reference herein:

U.S. Pat. No. 7,073,517, issued to Burnette III, discloses a hair cutting guide, for use by a hairdresser in cutting the hair of a person using scissors, having a pair of guide halves that are hingeably attached and selectively enter an open position and a closed position. Each of the guide halves have a plurality of teeth arranged along its longitudinal edges. The teeth have an inner surface that face the inner surfaces of the teeth in the other guide halve when the guide is in the closed position. Combs extend perpendicularly to the inner surfaces such that hair is extended transversely between the longitudinal edges and is held in place by the combs when the guide is closed. Straight cutting and point cutting is carried out by cutting with the scissors adjacent to the teeth along one of the longitudinal edges when the guide is in the closed position.

U.S. Pat. No. 4,517,998, issued to Furco, discloses a combination comb and sight gauge that can be manipulated using one hand so that the operator's other hand is free to cut or trim hair. The instrument is ideally suited for creating geometric hair styles.

U.S. Pat. No. 6,877,230, issued to Tapia, discloses an instrument for cutting hair comprises first and second members extending longitudinally in a direction generally perpendicular to a hinge axis of a hinge that connects the two members at proximal ends thereof. Each member has an arm and a leg. The legs have sockets in which blades are received. The arms comprise grip portions for grasping and actuating by a user's hand. During use, the actuation of the arms moves the legs in an arcuate path about the hinge axis similar to jaws on a pair of tongs. The instrument has a closed pinching or clamping position in which the blades meet each other in abutting relation. The method of using the instrument includes selecting blades from a group of tools comprising razor blades, thinning blades and backguards, disposing the selected blades in the sockets of respective legs, separating the legs, placing a lock of hair between the legs, clamping the blades on the lock of hair, and pulling or pushing the blades in a direction along the length of the hair to progressively cut hairs of the lock of hair.

U.S. Pat. No. 6,267,119, issued to Silva, discloses a haircutting guide-comb instrument for use in cutting head hair of a human being and including a pair of elongated legs superimposed over one another to clasp hair of the human being in between said legs with a bias spring engaged about the terminal ends of the legs to urge them in engagement with one another and an anchor at the terminal ends securing the bias springs to both of the elongated legs.

U.S. Pat. No. 6,135,123, issued to Grassi and Kovach, discloses a hair cutting guide comprising an upper clip and a lower clip is disclosed. A pivot pin interconnects the upper and lower clips allowing rotation of the upper and lower clip with respect to each other. A spring is mounted around the pivot pin and engages the upper and lower clips and urges them into engagement with each other. The upper clip includes a toothed ridge and the lower clip includes a groove which mates with the toothed ridge. The lower clip also includes a toothed ridge which mates with a groove in the upper clip.

U.S. Pat. No. 5,427,122, issued to Hamilton, discloses a hair-cutting guide having two interconnected plate members which align to compress and sandwich hair therebetween to be cut along an edge of the aligned plate members.

The inventions heretofore known suffer from a number of disadvantages which include not being easy to use; not being easily accessible; not providing a desired outcome; being expensive; not being safe to use; and requiring additional parts and steps.

What is needed is a hair cutting device that solves one or more of the problems described herein and/or one or more problems that may come to the attention of one skilled in the art upon becoming familiar with this specification.

FIG. 1 illustrates a front perspective view of a hair cutting device, according to one embodiment of the invention. The hair cutting device 100 includes an elongated positioner 102 which includes a first end 104, a second end 106, a first-end couplet 108, a second-end coupler 110, a peg 112, a first surface 114, a wedge 116, a wedge gap 118, a gravity field orientation sensor 120, a sensor attachment 122, and a second surface 124. The hair cutting device allows a user to cut their own hair or the hair of another quickly and accurately.

The first surface 114 includes a peg 112 to help hold the hair without pinching. There may be a plurality of pegs 112 disposed in a specific orientation, such that in embodiments where pegs intersect, the pegs 112 facing one another do not contact one another. The peg 112 may be any number of shapes or sizes.

The second surface 124 includes a gravity field orientation sensor 120 to sense angular orientation. The gravity field orientation sensor 120 is disposed on the second surface 124 of the first elongated positioner 102. As shown, the gravity field orientation sensor 120 is mounted on a sensor attachment 122. The sensor attachment 122 allows the gravity field orientation sensor 122 to rotate such that specific angled cuts may be made with ease. One example of a gravity field orientation sensor 120 may be such as, but not limited to, a bubble level as described in U.S. Pat. No. 2,750,677, issued to Wirth, which is incorporated by reference herein for its supported teachings.

The positioner 102 includes a first end 104 and a second end 106. The first end 104 includes a first end coupler 108 configured to selectably couple to the second end 124, by a second end coupler 110. One example of a selectably couplable attachment mechanism 128 may be such as, but not limited to, a snap fastener member as described in U.S. Pat. No. 3,715,783, issued to Parks et al., which is incorporated by reference herein for its supported teachings.

The positioner 102 includes a wedge 116 alongside one edge of the positioner 102 to allow for a more textured cut to be made on hair without necessitating the user manually texture it. In some embodiments, there may be a plurality of wedges 116. As shown, the wedge 116 is trapezoidal in shape and includes three sides, however in other embodiments the wedge may be any number or shapes and sized. In some embodiments, the wedges may have pointed or rounded ends.

FIG. 2 illustrates a hair cutting device 100 including a positioner 122 that includes first end 102, a second end 104, a coupler 108, a plurality of wedges 116 and a plurality of wedge grooves 118. As shown, the user is using the wedges 116 and wedge grooves 118 to texture the cut of the hair, such that when the user brushes or adjusts the hair after cutting, the tapered sections meld with the flat sections and leave an aesthetically pleasing look. As shown, when in a closed position, the wedges 116 and wedge grooves 118 line up such that each wedge 116 and wedge groove 118 line up with the other set of wedges 116 and wedge grooves 118. This allows the hair 200 of a user to be lined up as desired with a second surface 124 of the hair cutting device 100 such that the hair 200 may be quickly and easily cut.

FIG. 3 illustrates a hair cutting device 100 comprised of a single flexible positioner 102 configured to couple a first end 104 to a second end 106. The hair cutting device 100 as a single positioner 102 is shown in an open position. The first end 104 has s coupler 108 that is configured to couple to a coupler 110 of a second end 106 by a coupling mechanism.

The illustrated embodiment has the coupling via a snap, however in other embodiments there may be any number of coupling mechanisms, such as clips, clasps, snaps, hook and loop, mechanical fasteners, and the like and combinations thereof. The center section is shown to have no pegs 112, to allow the hair cutting device 100 to fold in on itself without interference. The pegs 112 are arranged in a particular orientation 304 (shown here as staggered rows 302) such that they do not interfere with each other when the hair cutting device 100 is folded. Further shown, the pegs are divided into a plurality of groups 300 such that a single piece unit when folded is not hindered by attempting to fold over or through a peg 112.

FIG. 4 illustrates a hair cutting device 100 comprised of a single flexible positioner 102 configured to couple a first end 104 to a second end 106. The hair cutting device 100 as a single positioner 102 is shown in a closed position. There is shown pegs 112 interlocking such that they perform their intended function without interfering with one another. Further shown is the first end 104 and second end 106 connectors, 108 and 110 respectively, closing and locking the device in place. The center of the hair cutting device is shown folded.

FIG. 5 illustrates a hair cutting device 100 comprised of multiple elongated positioners 102. There is a first elongated positioner 102 with a first and second end, 106 and 118 respectively, as well as a second elongated positioner 400 with a first and second end, 104 and 504 respectively. The first positioner 102 includes a first coupler and a second coupler, while the second positioner 400 also includes a first coupler 502 and a second coupler 504.

The couplers on the first ends of the first and second positioners, 102 and 400, are designed to be selectively couplable such that the ends may be attached and detached at will. The couplers on the second ends of the first and second positioners, 118 and 504, are designed to be hingedly coupled and not able to be detached. In some embodiments, the couplers on the second ends may be selectively couplable or may be coupled other than hingedly.

Further shown is a wedge gap 500, which divides each wedge 506 from adjacent wedges 506. This allows the hair placed within the hair cutting device 100 to be accessed by a cutting device in a tapered format such that the hair is not required to be cut straight across. Also, each wedge gap 500, like each wedge 506, is shown to line up with the opposite wedge gap 500 and/or wedge 506 such that wedge gaps 500 and wedges 506 do not overlap. In other embodiments, it may be beneficial to have other configurations wherein there are intersection between wedge gaps 500 and/or wedges 506, or the wedge gaps have other geometric or irregular shapes and/or different sizes.

FIG. 6 illustrates a hair cutting device 10 comprising a first and second elongated positioner 600. The first and second elongated positioners 600 are connected by a coupler 602. The connectors, 108 and 110, are shown as a different coupling embodiment. In this embodiment, the top connector 108 includes a hinged coupler as well as a snap coupler. In some embodiments, the hinged coupler attaches to the snap coupler while pressing the ends together, thereby holding the ends tight. The bottom connector 110 is shown to attach to the front of the end, however in other embodiments may attach instead to the snap coupler of the top connector 108.

One example of a selectably coupleable attachment mechanism 28 may be such as, but not limited to, a snap fastener member as described in U.S. Pat. No. 3,715,783, issued to Parks et al., which is incorporated by reference herein for its supported teachings. One example of a coupling mechanism 30 may be such as, but not limited to, a pin as described in U.S. Pat. No. 1,226,540, issued to Lauletta, which is incorporated by reference herein for its supported teachings.

FIG. 7 illustrates a hair cutting device 100 comprising a single elongated positioner 600. The elongated positioner 600 is shown to be folded a position relatively central on the elongated positioner 602, such that the first and second ends, 104 and 106, are able to couple to one another through their respective couplers, 106 and 108 respectively.

In operation of one embodiment of the hair cutting device, the user combs the desired hair to be cut. The user then assays the hair's thickness, the hair's thickness correlates to a corresponding plate member. The plate members may vary according to the variety of hair thicknesses. Next, the user couples the selectably coupleable pegs to the elongated positioners. The user then clamps the hair together between the first and second elongated positioners. Then, the user assays the elongated guide members to a desired hair length/style. The user then pulls the elongated positioner to the desired hair length/style. The user may assay the gravity field orientation sensor to a desired hair length/style, adjusting the gravity field orientation sensor to a desired angle/degree corresponding to a desired hair length/style. The user then cuts the desired hair to be cut along the elongated positioners. The following steps may be repeated until the desired hair/style is finished.

It is understood that the above-described embodiments are only illustrative of the application of the principles of the present invention. The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiment is to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.

For example, although the figures illustrate an elongated positioner, one skilled in the art would appreciate that the guide member may vary in size, shape, color, configuration, design, length, width, thickness, orientation and still perform their intended function.

Additionally, although the figures illustrate multiple varying coupling mechanisms, one skilled in the art would appreciate that the attachment and coupling mechanisms may vary in size, shape, color, configuration, design, length, width, thickness, orientation and still perform their intended function. Moreover, examples of an attachment and/or coupling mechanism may be such as, but not limited to: pins, snaps, hooks, hook and loops, adhesives, magnets, etc. and still perform their intended functions.

In addition, one skilled in the art would appreciate that there may be a degree increment adjustment that may be able to make degree increment adjustments such as, but not limited to: 5, 10, 15, 30 degree increment adjustments such that the device may still perform its intended function.

Furthermore, although the figures illustrate a pair of scissors as a cutting device, one skilled in the art would appreciate that the cutting device may vary and still perform its intended function. For example, the cutting device may be such as, but not limited to: scissors, clippers, razor blades, etc.

It is also envisioned that one skilled in the art would appreciate that the pegs of the hair cutting device may vary in size, shape, color, configuration, design, length, width, thickness, orientation and still perform their intended function. In addition, examples of pegs may be such as, but not limited to: bristles, spikes, pegs, teeth, Velcro, etc. and still perform its intended function.

It is expected that there could be numerous variations of the design of this invention. For example, the gravity field orientation sensor of the hair cutting device may vary in size, shape, color, configuration, design, length, width, thickness, orientation and still perform its intended function. In addition, the gravity field orientation sensor may be such as, but not limited to: a bubble level, a mason's level, a carpenter's level, a torpedo level, a post level, a line level, an engineer's precision level, an electronic level, a slip indicator, and/or a clinometer; and still perform its intended function. Furthermore, the oil contained within the gravity field orientation sensor is denser than water and/or spirits normally used in carpentry levelers. The denser oil enables the gravity field orientation sensor to slowly adjust to the movement of the device.

Finally, it is envisioned that the components of the device may be constructed of a variety of materials such as, but not limited to: plastic, metal, metal alloys, plastic composites, metal composites, glass, carbon fiber, and/or wood, and still perform its intended function.

Thus, while the present invention has been fully described above with particularity and detail in connection with what is presently deemed to be the most practical and preferred embodiment of the invention, it will be apparent to those of ordinary skill in the art that numerous modifications, including, but not limited to, variations in size, materials, shape, form, function and manner of operation, assembly and use may be made, without departing from the principles and concepts of the invention as set forth in the claims.
